What do the other reset options mean?
When you’re resetting your iPhone it presents you with a plethora of different options, and it can be confusing to decide which ones to choose. Typically, you’re looking to perform a simple factory reset, but here’s an explanation of what the other options do so you can choose the best reset for your needs.
If you sell your phone or give it to someone else, the only command that safely erases everything and returns your phone to its original state is Erase all content and settingsas described above.
Reset all settings
This command resets all the settings on your iPhone to their default values, that is, all network settings and preferences. This is not an option to erase all content, as it only resets system settings. All your applications, data, documents and files are preserved as is.
reset network settings
Sometimes you just need to update your network settings to set up a better connection. Choosing this option resets your network settings, clears the cache, and deletes any temporary files you may have stored on your device. It’s great for those who have trouble with their Wi-Fi connections.
Reset keyboard dictionary
This is a simple solution to auto-fix crashes and involves clearing your keyboard’s dictionary history. Your iPhone’s autocorrect system sometimes messes up a sentence or word that was fine in its original form and this will solve the problem of getting suggestions for typos and irrelevant words when typing.
